"Rules of Engagement" on CBS at 8:30pm ET. Sixth season spring premiere. I've read about the reinforcement bubbles that we put ourselves into with the power of the internet. That because we can choose the people we associate with on social networking sites and get our news and entertainment information from selectively culled sources, it's less likely that we'll run into dissenting opinions. My version of this is that thanks to Pajiba I end up assuming shows like this are cancelled at the end of every season because no one ever talks about them and then they come back and I'm baffled every single time.

"Up all Night" on NBC at 9:30pm ET.

"Mudcats" on History at 10:00pm ET. Because what television needed was two shows about noodling catfish on competing networks.

"Punk'd" on MTV at 10:00pm ET. Ninth season premiere. Speaking of shows I didn't realize were still on, there's this thing too. Tonight's victim is Justin Bieber.
